Question regarding the viability of bitcoin in the long term. From my understanding, the security of bitcoin comes from miners who verify the blockchain. What happens when there is so much halving that the reward for mining bitcoin is extremely low and the cost of verifying the blockchain for the miners exceeds the reward of their bitcoin?
Miners still receive Bitcoin from transaction fees. And if they are not happy with their earning, they can simply stop mining which makes the diff decreasing. Satoshi Nakamoto has already thought about this issue and thats why bitcoin has been trusted for many years like that. Currently, the team behind bitcoin blockchain also makes a lot of changes in order to make bitcoin becomes even stronger and suitable for all the people. Therefore, nothing needs to be worried about. Just chill with your coin and hold them
